 In this module, we shall attempt to recap whatever we have studied so far. Of course, we would not be looking at each and everything, but in this module, we would be trying to assess the efficacy of the pedagogical approach we have taken so far. This would attempt to assess the learning achievement of you, the students. And of course, this would have implications for me to further continue with the learning process. And in light of today's feedback, we might be improving our process of learning and development. So in this segment, we shall attempt to assess efficacy of the learning process so far. With the help of a quiz, we would like to gauge the level of achievement of the students. This exercise should serve as a feedback for both myself and for yourself. So let's start this quiz. This is a hypothetical quiz. The question is in front of you. And I'm going to read out which of the following cannot be bought and sold on a solemn basis. Amazon. So this is the question in front of you. You should attempt to answer this. Of course, this is a video lecture. I would assume and I would expect that you would write down your answer. If your answer is B, you can write down. If your answer is D, of course, you can note it down accordingly. I'm sure all of you would have different answers to this question. Some of you might think that this is A. Others may think that this is D. And of course, some of you would definitely think that this is either B or C. If, for example, one of you says that this is Burj Khalifa. And if I click on that one, let us see whether this is the right answer. I'm going to click on Burj Khalifa. That is actually the right answer. Burj Khalifa cannot be bought and sold on a solemn basis. Why? Because this is a specific item. And in this case, it's a unique item. In case of Salam, anything which is specific cannot be bought and sold on a solemn basis. For example, if I say that I sell this pen on a solemn basis to you for a price of 100 rupees, this would not be a valid Salam sale. Because in case of Salam, no one can sell a specific item. Of course, we can sell items, generic items with some specific details. So I can sell iPhone 12 Pro Max, color silver and with other specification to anyone on a Salam basis because there would be so many iPhone 12 Pro Max of that specification available in the market. Now Burj Khalifa cannot be bought and sold on a Salam basis because of the injunction in one of the Ahadith that any produce of a specific field cannot be bought and sold on a Salam basis. So similarly, anything which is specific and you say this thing, my this phone or something else I should be able to buy and sell on a Salam basis. This is not acceptable. Now, other questions, other answers like B in case of Rebuvi commodities. What are Rebuvi commodities? Rebuvi commodities are six. They include wheat, barley, salt, dates, silver and gold. Of course, these six commodities can only be exchanged with themselves on a spot basis. So if I want to exchange wheat for wheat, it is possible only on a spot basis. However, these commodities can be bought and sold on a Salam basis because in a trade, wheat versus money. So the counter values are different. This is something we have already explained in one of our modules previously. In case of C, of course, cars as I said, cars are generic commodities or things which can have some specifications. So I can sell a Honda, Civic, Model so and so, black color because there would be so many such cars available in the market. So cars can be bought and sold on a Salam basis. And the question, the answer about Amazon, so anything which is listed on Amazon cannot be bought and sold on a Salam basis. This is wrong because only those things which are not permissible, they cannot be bought and sold anyway whether on a Salam basis or Morabha basis. Amazon is only a commodity exchange. It is an exchange. It is a bazaar. It is a market. And you can buy anything from a bazaar, from market, from Amazon as long as the thing you are attempting to buy and sell is actually halal.
